2:3 Portrait Photo Calculator
2:3 portrait — 3:2 turned vertical. Ideal for portrait prints and vertical photo crops.
2:3 is the portrait twin of 3:2 — 2000×3000, 4000×6000 and any DSLR vertical hold with the camera rotated. Prints at 6×9, 8×12 and 12×18 fill edge-to-edge in portrait. Use it to size vertical photo exports, book covers and poster crops without leaving bars.

Exact ratio: 2:3 · CSS: aspect-ratio: 2 / 3 · padding-top fallback: 150.00%
Formula
height = width × 3 ÷ 2
width = height × 2 ÷ 3
// padding-top fallback: 150.00% — keeps layout stable before the image loads
aspect-ratio: 2 / 3 — modern replacement for the padding hack

When to use 2:3
- Vertical DSLR stills (rotate 3:2)
- Portrait prints 6×9, 8×12, 12×18
- Book covers & poster vertical crops
Pitfalls to avoid
- Feeding a 2:3 vertical into a 16:9 slideshow pillars it heavily
- Instagram portrait is 4:5, not 2:3 — 2:3 is taller and gets cropped
CSS snippet
Modern:
.frame { aspect-ratio: 2 / 3; width: 100%; overflow: hidden; }
.frame > img { width: 100%; height: 100%; object-fit: cover; }Legacy padding hack (for very old browsers):
.wrap { position: relative; width: 100%; padding-top: 150.00%; }
.wrap > * { position: absolute; inset: 0; }Pair with object-fit: contain to letterbox without cropping, or cover to fill and crop safely.
